Nope. What you'll need is to setup one of the two XMPP / Jappix addons. XMPP is not connected to Hubzilla. I don't know if it's possible to have the same WebFinger since XMPP is setup differently (via TXT records).

I'm not sure if those two XMPP addons are updated since those were from Friendica when Mike first created Red/Hubzilla. I've alriady forgotten how to set it up myself.

If you want hassle free setup , you can use #yunohost which have #hubzilla package and #xmpp server with #ldap support. You just need to set up reverse proxy for bind as explained in the post and you are ready to use the xmpp with all your users on hubzilla because of ldap.
